“…The vibrations decrease on average from 13% to 15% but they may be reduced as much as 30%. The authors [5] suggest that a seat suspension has been almost a universal feature of agricultural tractors during the last 30 years. The suspension system was introduced to enable the operator to manage the machine in a more comfortable and easier way, which has resulted in increased work productivity.…”

The paper presents the recorded vibrations that affect the operator’s body when an agricultural tractor moves along three types of agrotechnical surfaces, i.e. asphalt, an alfalfa field, and a field path, and when seven different tractor seat upholsteries are used. The research was performed in accordance with the HRN ISO 2631-1 and HRN ISO 2631-4 standards. The tractor used in the research was an IMT 560 and the duration of the measurement was 30 minutes, which was repeated three times for every tractor seat upholstery type. The research was exploitative. The measurements were performed using an MMF VM30 meter. The paper reveals a different level of vibrations in dependence with different surfaces and seat upholsteries. The fewest vibrations were produced by asphalt, and the best upholsteries are memory foam and sponge.

“…Firstly, we have to make note that ploughing in rural communities was and is still done on a small scale, an average family usually ploughs 1-3 hectors of land which requires 1-2 weeks of labour when using cattle compared to a few hours when using a tractor. However, when we come back to ergonomic implications of using a tractor, the driver sitting on the small tractor seat the whole day and been subjected to vibrations and sound of the tractor, not to mention the pollutants from the diesel exhaust fumes ( Figure 2) and bumping up and down from the seat can affect the users [8][9][10][11] negatively as outlined by Shohne Daeijavad, C.R. Mehta, Roberto Deboli, C.R.…”

Ergonomics is the scientific field of knowledge concerned with the understanding of interactions between humans and systems or machines and furthermore the profession that applies theory, principles data and methods to design in order to optimize human well-being and overall system performance. Therefore, to further optimize the ergonomic performance the environment need to be incorporated in the human system interaction definition to form a tripartite symbiotic interphase. The purpose of this article is to discuss the role of ergonomists in improving the human, system and environmental conditions using the pragmatic approach of defining human factors ergonomics.

“…Deboli et al had done the whole body vibration measurement of horizontal and vertical transmissibility of an agricultural tractor seat. Finally, they had drawn the conclusion that the rolling and pitching effects can be reduced by using specific suspension systems along the horizontal and lateral directions [16]. Humphreys et al have investigated the system dynamics which included the human operator and biodynamic feedthrough.…”

Special equipment drivers often suffered from vibration which threatened their physical and mental health. In order to study the riding comfort of a special equipment cab, a hammering experiment has been carried out on it by acceleration sensors. According to the test results, the natural frequency has been calculated which was compared with the result analysis by the finite element method. Next, the equipment operating condition test on a flat road was done. The vibration characteristics of the whole vehicle were obtained later. The results show that the cab vibration and the finite element results agree well, but the natural frequency of the cab is close to the vibration frequency of the human body. And this is not conducive to long-term operation of the drivers. In order to improve the human operational comfort, it is necessary to reduce its natural frequency during the cab structure design process. The research in this paper can provide help for the similar human-machine operation comfort study and product design.
